Hello. After 3 weeks I would be a little concerned as to why Tristan is not any better. I would not use the Mucinex as this can dry out the secretions & actually make things worse. If your veterinarian has not done chest x-rays, this would be the very next step to see if there is something else going on. In the meantime, I would try doing some steam therapy with him. Sometimes the warmth & moist heat will help ease the breathing, but please try to have him seen soon. Thanks for using Petco Pet Education Center, formerly Petcoach.
